Our climate is changing, for the worse. Its predictable reliability belongs to an older generation. Scientists can already see how warmer ocean temperatures, melting arctic ice, and higher sea levels contributed to making Sandy as terrible as it was.

Just last year, once-in-a-generation Irene arrived—becoming the fifth-costliest hurricane in U.S. history, causing 49 deaths and $19 billion in damage. But Irene was a breeze by comparison to Sandy.

We must stop this "once-in-a-generation." thinking. It is dangerous, misleading, and irresponsible. Those who still believe that the powerful new floods, fires, droughts and storms are once in a generation events are the ones blocking the way to doing something about climate chaos.

haha... and you're what, suggesting that you have all the answers? From what I can see of our present scientific ability, and I follow it rather closely, it does not appear to me that we have ANY of the answers.

Canada, with its massive dirty tar sands deposits, is ground zero in the fight to stop climate change. In fact, NASA’s leading climate scientist has written that if Canada fully taps its tar sands deposits, it will be “game over for the climate” -- that’s why the fight over Transcanada’s proposed Keystone XL pipeline is so critical.

So when our friends fighting the fossil fuel industry north of the border call us and ask for urgent help, we need to be there for them.

Right now Canada’s Conservative government is trying to ram through a treaty that would allow Chinese oil corporations to control the future of the tar sands. FIPA, the Canada-China Foreign Investment Protection Agreement, could give multinational corporations sweeping powers to sue the Canadian government to stop environmental protections on the tar sands, locking in the current Canadian government’s corporate-friendly policies for decades.

The stakes are huge: If FIPA passes -- which could happen as early as this Friday -- then future Canadian governments could be legally compelled to allow tar sands mining. And the consequences for the planet would be catastrophic.

SumOfUs members have already helped raise a huge outcry against FIPA in Canada. One Member of Parliament told our campaigner that the tens of thousands of emails to Parliament, hundreds of letters to the editor, and dozens of major news stories our campaign has generated in the last two weeks has been the most effective pressure campaign he's ever seen.

From south of the border, we can’t write to Canadian Members of Parliament. But if anyone knows what it’s like to have a government in the pocket of big corporations, it’s Americans. We can help with the next critical phase of the campaign, along with our partners at LeadNow.ca -- blanketing the airwaves with emergency radio ads this week in the local districts of key Members of Parliament.

Can you donate $20, the cost of one radio ad spot in a key Canadian politician's hometown, to help stop FIPA and protect the tar sands from greedy multinational corporations?

Thousands of American members of the SumOfUs.org community are already fighting against the Canadian tar sands by challenging the Keystone XL pipeline. I was arrested along with Bill McKibben and more than a thousand others in front of the White House last year to oppose the pipeline. And the SumOfUs.org community raised $50,000 for the legal defense fund of Julia Trigg Crawford, who is trying to stop Transcanada from seizing her family farm in Texas to build the pipeline through it.

Hurricane Sandy has given us another huge wake-up call about the consequences of runaway climate change. And the prognosis for the climate could be bleak if this treaty passes. Chinese multinational fossil fuel corporations will be able to buy up major tracts of the tar sands in Canada, and then be able to legally block any future Canadian governments from cracking down on pollution from the tar sands.

This treaty is could be rammed through as early as this Friday, just two days from now -- unless Canadian activists can effectively pressure enough politicians in Canadian Prime Minister Stephen Harper’s own party to make him back down.

Just $20 will buy one 30-second play of an ad on radio in a key district, and every donation means that we can play the ad one more time -- making it more likely to be heard by more people, and amplifying our impact.

Help get our people-powered radio ads on the air tomorrow by pitching in $20, or whatever you can afford.

SumOfUs.org members from around the world, including tens of thousands of Canadians, have already stood up to fight corporate dominance of American politics. They helped take down the Heartland Institute and they helped fund our campaign to push Google to leave the Chamber of Commerce. Now we need to stand together to stop the sale of the Canadian government to Big Oil.
